Benefits of technology

The present invention relates to a bicycle apparatus that includes an assist motor and an ABS unit. The control device of the bicycle apparatus is configured to reduce the output of the assist motor in the first direction when the operating device is operated to rotate the motor. Additionally, the control device is configured to reduce the hydraulic pressure that is applied to the brake device when the operating device is operated, and to rotate the assist motor in the second direction. The technical effects of this invention include improved efficiency and better control of the bicycle apparatus.

Problems solved by technology

According to the bicycle apparatus described above, the size in not easily increased even when mounting an ABS unit.

first embodiment

[0033]Referring initially to FIG. 1, a bicycle 10 is illustrated that is equipped in accordance with a first embodiment. FIG. 1 is the outer appearance of an electrically assisted bicycle (hereinafter referred to as “bicycle 10”). The bicycle 10 comprises a frame 12, a front wheel 14, a rear wheel 16 and a handlebar 18. The frame 12 forms the main body of the bicycle 10. The front wheel 14 and the rear wheel 16 are wheels which are rotatably attached to the frame 12. The handlebar 18 is operated for changing the orientation of the front wheel 14. The bicycle 10 further comprises a pair of brake levers 20F and 20R which are operating devices that are attached to the handlebar 18. The bicycle 10 further comprises a brake device 22F for applying a braking force to the front wheel 14, and a brake device 22R for applying a braking force to the rear wheel 16. The diameter of the front wheel 14 and the rear wheel 16 are substantially the same.

[0034]Each of the brake devices 22F and 22R are...

second embodiment

[0099]The bicycle apparatus 56 according to the second embodiment differs from the bicycle apparatus 56 according to the first embodiment in the points described below, and comprises configurations that are substantially the same as the bicycle apparatus 56 according to the first embodiment in the other points. In the description of the bicycle apparatus 56 according to the second embodiment, the same reference symbols are given to configurations that are shared with the bicycle apparatus 56 according to the first embodiment, and some or all of the descriptions of the configurations thereof are omitted.

[0100]FIG. 5 shows the electrical or the mechanical connection relationships of the bicycle 10 (refer to FIG. 1). The broken lines of FIG. 5 show the electrical connection relationships of the bicycle 10. The solid lines of FIG. 5 show the mechanical connection relationships of the bicycle 10.

[0101]The bicycle apparatus 56 comprises an ABS unit, which is driven by the assist motor 36,...

modified examples

[0119]The descriptions relating to each embodiment are examples of forms that the bicycle apparatus according to the present invention can take, and are not intended to limit the forms thereof. The bicycle apparatus according to the present invention can, in addition to the embodiments, take the forms of the modified examples of the embodiments shown below, as well as forms that combine at least two modified examples that are not mutually exclusive.[0120]The control device 60 of a modified example executes the step S6 and the step S7 simultaneously in the ABS operation control. The control device 60 of another modified example executes the step S7 before the step S6 in the ABS operation control.[0121]According to the control device 60 of a modified example, the step S16 to step S18 are omitted from the step shown in FIGS. 3 and 4, in the ABS operation control.[0122]According to the control device 60 of a modified example, the step 19 is omitted from the step shown in FIGS. 3 and 4, ...
